Improvements in semiconductor memories |
(57) A bit-line load for a static random access memory incorporates a load comprising
a diode, and current limiting means in series with the diode, the diode/limiter assembly
being shunted by a current source. This overcomes both the V
dd drop problem and the high write cycle current flow experienced with conventional
bit line loads.
